Title: Improvements in and relating to the simulation of drinks
Inventor: DUNLOP ROBERT GEORGE
IPC: G09F19/10
Filed: 1960-10-12
Abstract: A method of producing an article simulating a drinking glass, containing a drink, comprises pouring in the liquid state into a drinking glass a synthetic resinous material which sets to simulate the drink, the pouring being effected under conditions of temperature which does not harm the glass and the resinous material being set by cooling.  A thin layer of unplasticized resinous material is poured on to the exposed surface of the resinous material to produce a hard, smooth surface.  To produce froth the resinous material is agitated by a paddle or blowing device or a separate batch of resinous material may be prepared and added to simulate froth.  Bubbles may be produced by introducing a wire into the resinous material or by agitating. Cherries, olives, pieces of ice or lemon may be added, or simulations thereof.  The resinous material may be produced from materials such as methyl methacrylate, butyl methacrylate, ethyl acrylate or Tensol Cement No. 7.  "Tensol" is a Registered Trade Mark.  Example I.  To simulate a champagne drink.  The resinous material comprises 60 parts Tensol Cement No. 7 suitably coloured with an oil-soluble dye, mixed with 6 parts benzoyl peroxide and 40 parts dibutyl phthalate.  The mixture is poured into a champagne glass and a fine wire inserted and withdrawn several times to produce streams of bubbles.  The material is allowed to cool and a mixture of 10 parts Tensol Cement No. 7 with less than 0.5 parts of accelerator poured over the surface to produce a hard surface.  Example II.  To simulate a beer drink.  The suitably coloured resinous material is poured into a beer glass and allowed to set. To produce froth a mixture of 25 parts Tensol Cement No. 7 with 2.5 parts of accelerator is added.

Title: Improvements in or relating to apparatus for measuring electrical energy
IPC: G01R11/00
Filed: 1931-12-18
Abstract: 378,752. Supply and power meters. SZILAS, O. and SZEKELY, N., 67, V÷r÷smarty Utca, Budapest. Dec. 18, 1931, No. 35094. [Class 37.] Measuring or recording apparatus for electrical energy takes into account transmission or transformer losses occurring on either or both sides of the meter, additional torque proportional to the losses independent of the load being provided on the meter movement by the inclusion of an ohmic resistance in the current coil, and losses depending on the load by a resistance in the potential coil. The losses only may be measured. The auxiliary transformers and ohmic resistances may be located in a single casing outside the meter, or the resistances may be mounted on the transformers, or within the oil tank of a transformer. Terminal arrangements on the external apparatus correspond with those on the meter. In one circuit, Fig. 1, an additional torque corresponding to the no-load losses of the main transformer P, S is provided, a variable resistance n being connected across the load M and in circuit with the current coil a of the meter. The potential coil f of the meter is connected in series with a variable resistance m in parallel with the secondary of a current transformer p<1>, s<1> in the current circuit of the meter, the resistance m introducing a potential drop equal to that in the main transformer. The meter circuits above described may be connected to the mains through current and potential transformers in the normal way. For measuring the no-load losses separately, Fig. 3, the current coil a of the meter is fed through a variable resistance n from a potential transformer p<3>, s<3>, the potential coil f being connected normally. The winding losses are measured separately by feeding the current coil of the meter with the load current, the potential coil being supplied solely from the transformer p<1>, s<1> and resistance m, Fig. 1. On polyphase lines, the circuit arrangements above described need only be connected in one line or phase. The useful energy on the high voltage side may be measured by connecting the resistances in opposite sense with respect to that described above.

Title: Improvements in amusement apparatus
IPC: A63G19/20
Filed: 1953-12-17
Abstract: 749,891. Switches held set and freed mechanicallly. BRYAN, W. E. Dec. 20, 1954 [Dec. 17, 1953; June 16, 1954], Nos. 35135/53 and 17624/54]. Class 38(5) [Also in Groups XV and XVIII] An amusement apparatus, such as a mechanical horse, (see Group XV) is driven by an electric motor 34 controlled by a mercury switch 83 operated by coin freed mechanism, a hand lever and. a mechanical timing arrangement. After insertion a coin, on reaching track 67, knocks the end of arm 76 causing projection 95 to knock levers 79 and 80 out of alignment which allows lever 82 to be pulled across against peg 87 which carries arm 86 across until cut out 90 engages catch 89 so that arm 86 is held and peg 85 no longer prevents switch 83 from closing. Switch 83 can now be closed by moving a lever 91 through linkwork by a control knob 9 when motor 34 will be started and ratchet wheel 75 will be rotated by a pawl 74 reciprocated by the motor. As pin 98 rotates, it moves lever 82 and hence levers 79. 80 back to their original positions. When rotation of wheel 75 is almost complete, pin 98 engages arm 86, disengages catch 89 and arm 86 is pulled back by spring 108 and peg 85 engages member 84 to open the switch 83 to stop the motor. On falling through track 67, the larger of the coins will engage the end of arm 69 whose other end will rise so that pin 71 pushes arm 96 and hence arm 72 upwards. In this position of arm 72, wheel 75 will be rotated more slowly so that the apparatus operates for a longer time. The switch 83 may be returned to the " off" position at any time by lever 9.

Title: Torque limiting coupling
IPC: F16D43/20
Filed: 1973-07-24
Abstract: 1394920 Positive clutches TWIN DISC Inc 24 July 1973 [24 Aug 1972] 35181/73 Heading F2C In an overload release clutch wherein torque transmitting balls 3 carried by holes 32<SP>11</SP>... 43<SP>11</SP> in a carrier 6 normally engage recesses 32, 32<SP>1</SP>...43, 43<SP>1</SP> in driving and driven clutch discs 4, 5 urged together by springs 22, 23, the balls 3 ride out of the recesses 32, 32<SP>1</SP>...43, 43<SP>1</SP> on overload and move circumferentially into reset recesses 44...48 in the driving disc 4 which, during clutch disengagement is held at a predetermined distance from the driven disc 5 by spacing blocks 8 carried by a disc 7 which is resiliently connected to the ball carrier 6. The spacing blocks 8 abut a shoulder 71 on a driving shaft 1 and normally project into recesses 70 in the driving plate 4. When, on overlaod, the balls 3 ride out of the recesses 32, 32<SP>1</SP>...43, 43<SP>1</SP> the driving disc 4 is moved axially away from the driven disc 5 against the bias of the springs 22, 23. The following circumferential movement of the balls 3 rotates the carrier 6 and spacing block carrier disc 7 relative to the driving disc 4 so that when the balls 3 engage the reset recesses 44...49 the spacing blocks 8 abut the surface of the driving disc 4 and hold it at a predetermined distance from the driven disc 5. The spacing between the disc 4, 5 permits free relative rotation between the discs. An abutment 53 rotatably fast with the driving shaft 1 abuts the end of circumferential recesses 52, 61 in the ball carrier 6 and spacing block carrier 7 in the clutch disengaged position to prevent movement of the carrier 6 and balls 3 beyond the reset recesses. The circumferential extent of the recess 52 in the ball carrier 6 exceeds that of the recess 61 in the spacing block carrier 7 to permit relative rotation of the ball carrier 6 and spacer carrier 7 during clutch disengagement. Springs 9, 11 resiliently connecting the carrier discs 6, 7 thus bias the ball carrier 6 in a reset direction during clutch disengagement. To reset the clutch the driving disc 4 is rotated reversely or the driven disc 5 rotated forwardly whereupon the bias of the carrier disc 6 urges the balls 3 into engagement with the driven disc recesses. Further rotation of the driving or driven disc moves the balls 3 and carrier 6 relative to the driving disc 4 until the balls 3 re-engage the driving disc recesses 32<SP>1</SP>...43<SP>1</SP> and the spacing blocks 8 re-enter the recesses 70. The driving disc 4 is splined to a sleeve 13 which is itself splined to the driving shaft 1. The torque at which the clutch disengages on overload is adjusted by adjusting the position of the sleeve 13 and thus the pressure of the springs 22, 23. The balls 3 and driven disc recesses are unequally spaced circumferentially to permit clutch engagement in only one relative circumferential position of the driving and driven members.

Void [Abridged as open to inspection under Sect. 91 of the Acts, Jan. 10, 1934]. [Class 98 (i).] To facilitate the removal of the exposed portion of a rollfilm for development while leaving the unexposed portion ready for continuing the exposures, the sensitive film is divided into two or more lengths c, c spaced apart on the backing paper a, and the backing paper in the interspaces is perforated either crosswise as at b, Fig. 1, so as to leave a triangular threading tongue on the free end of the part carrying the unexposed length of film when the paper is severed at the perforations, or along a series of lines d, b<1>-b<4>, Fig. 2, so as to leave a trapezoidal tongue. The hatched portions e of the paper, Fig. 2, may be gummed on the back so that when the exposed portion of the film is rolled up, the paper may be stuck down at these portions, thus facilitating severance of the paper to leave a tongue of the desired shape on the portion carrying the unexposed length of film.

Title: Foundry moulding composition
Inventor: HOLLIS JOSEPH BERNARD
IPC: C04B28/26
Filed: 1968-07-24
Abstract: 1,267,919. Foundry moulds. MATERIALS & METHODS Ltd. 18 July, 1969 [24 July, 1968], No. 35281/68. Heading C3N. Foundry moulds are produced by adding to particulate materials coated with an alkali metal silicate from 10 to 100%, preferably 40-60%, by weight, based on the weight of the alkali metal silicate of a hardening agent selected from sodium formate or an hydroxide of an element of Group II of the Periodic Table or any combination thereof before or during the shaping operation, and hardening the finished article in the absence of added carbon dioxide. The preferred hardening agent is hydrated lime which is advantageously added in the form of an aqueous suspension. The hardening rate may be accelerated by adding a reducing agent, e.g. calcium silicide or ferrosilicon in an amount of less than 1% by weight. The alkali metal silicate may be sodium or potassium silicate preferably having a molar ratio of SiO 2 : Na 2 O(K 2 O) from 1.2:1 to 3.5:1, preferably 1.65:1 to 2.79:1. Refractory materials specified are silica, zircon, olivine, chromite, refractory grogs, crushed coke, carbon, graphite, silicon carbide, sillimanite, limestone, dolomite and chamotte. The hardening agents may also be used in conjunction with conventional hardeners such as dicalcium silicate, cements, basic slags and oxides and carbonates of elements of Group II of the Periodic Table.

Title: Photo-electric device for indicating the diminution of light
IPC: H01J40/00
Filed: 1947-12-31
Abstract: 661,654. Photo-electric cells. ELECTROWATT ELECTRICAL & INDUSTRIAL MANAGEMENT CO., Ltd. Dec. 31, 1947 [Jan. 18, 1946], No. 35322/47. Class 39 (i). [Also in Groups XL (b) and XL (c)] A device for indicating changes in light intensity by the control of the discharge current of a gas discharge tube with at least three electrodes of which one or more is photosensitive is characterized in that there is a weak preliminary discharge current through a starter gap which is regulated by a reactor to be less than the breakdown current of the starter gap for one given intensity of irradiation but greater than the breakdown current of the starter gap for a smaller intensity of irradiation, the starter gap being such that an unstable surge discharge occurs as soon as the breakdown current becomes less than the preliminary current as a consequence of diminished irradiation, the current of the surge discharge being at least periodically greater than the preliminary current so that it initiates a secondary discharge in another gap with at least one electrode separated from the starter gap. In Fig. 3 a preliminary stable discharge is maintained between the photo-electrode L and the electrode Z, this discharge having a capacity C in parallel with it and a resistance R in series. On reduction of the illumination the discharge becomes unstable and the resulting periodic increase in current causes sufficient ionization to trigger the main discharge between electrodes L and A which may be used to operate a relay E. To prevent the photo-electrode from being damaged by the main discharge it may be surrounded by an auxiliary electrode K, Fig. 4, to which it is connected by a high resistance W. Alternatively the photo-electrode may be placed between the two main electrodes and may be of grid-like form, Fig. 5 (not shown). To increase the breakdown voltage of the main gap the anode A may be surrounded by a glass tube D; the anode should have a small surface area and the cathode a large one. The filling may be of hydrogen but is preferably of one or more rare gases at a pressure up to or over 100 mms. The resistance R may be inside the tube or inside a separate air-tight container built on to the tube, and the condenser C may be similarly mounted. The resistance R may be replaced by a condenser which may comprise coatings on the inside and outside of the envelope. Alternatively the resistance R may be replaced by an ionization chamber, an illuminated photo-cell, or a thermionic valve. The device may be operated with D.C. or A.C. or pulse trains. The Specification as open to inspection under Sect. 91 also describes the trigger gap constructed as a separate discharge device which may be used to fire a separate discharge tube. The trigger tube may be combined with the resistance and condenser as described above. This subject-matter does not appear in the Specification as accepted.

Abstract: 842,895. Wheeled toys. MINIMODELS Ltd. Sept. 3, 1957 [Nov. 20, 1956], No. 35458/56. Class 132(3). A four wheeled toy adapted to be driven electrically on an insulating base, e.g. of plastic, carrying parallel conductor rails, has a current pick-up device to contact both rails and to constitute with two of the wheels a three point support by which substantially the whole weight of the toy is taken. As shown, the pick-up device comprises a roller 20 having a flange 9 to run between the two rails to steer the toy. The roller comprises cup-shaped parts 25, 26, Fig. 3, connected together with an interposed insulating disc 27 and having trunnions 28, 29 rotatably disposed in diametral bearing grooves such as 30, Fig. 5, in a lower ring 21 which with an upper ring 22 fitting within it forms an insulating housing. The ring 21 is rotatable on the chassis 10 within limits determined by abutment of trunnions 28, 29 against the end surfaces 8, Fig. 7, of cut away parts of ring 22 which is held stationary by upstanding tongues on the chassis and carries conductor strips 36, 37, Fig. 6, on its lower surface for contact with the trunnions. The conductor strips 36, 37 are connected to the positive and negative poles of the motor armature carried by the chassis 10 and through trunnions 28, 29, roller parts 25, 26 and rails 43, 44 to the positive and negative terminals of a supply source. A weight (not shown) on the chassis keeps the roller in good contact with the rails. The rear axle of the toy is driven by a reduction gear from an electric motor on the chassis and passes through the motor casing. The Provisional Specification describes a roller unit disposed in a metal housing and a front wheel axle mounted at opposite ends in circular and vertically slotted bearings so that the axle is inclined downwards and lifts the front wheel adjacent the circular bearing out of contact with the surface on which the toy runs.

Filed: 1930-11-25
Abstract: 365,253. Railway vehicle buffers. TURTON, PLATTS, & CO., Ltd., G., Meadow Hall Road Works, Wincobank, Sheffield, and HEWITT, F., Green Lawn, Green Lane, Dronfield, Derbyshire. Nov. 25, 1930, No. 35470. [Class 103 (v).] In a railway vehicle buffer of the kind in which a hollow plunger b sliding within the casing a is prevented from withdrawal therefrom by means of a retaining member fitted on one part and coacting with a shoulder on the other part, the retaining member is composed of a number of annularly disposed elements d that are capable of being inserted individually into and of being retained in their operative position, the object being to permit the use of a plunger of such shortened length that the head thereof contacts with the front of the casing a under extreme compression, while the casing may have either an integral or separate baseplate c. In the construction illustrated in Figs. 1 and 2 the elements d of the shape shown are inserted through an aperture f in the larger diameter portion of the casing a so as to engage a double annular groove e in the plunger b, the elements being worked into position by a tool until they form a complete ring adapted to co-operate with a shoulder f<1> on the casing, subsequent to which the aperture is closed by a cap g. If desired, the aperture f may be formed in the smaller diameter portion of the casing, or, as shown in Fig. 5, the elements may be inserted from the front of the casing by passing them along grooves k, j in the plunger and casing and subsequently inserting a closure key m. Or, when a detachable baseplate is employed, the elements may be inserted from the rear of the casing. In further constructions the elements d, either solid or in the form of springs, Figs. 12 and 13, or of a combined solid and spring construction, are disposed in a series of circumferentially arranged separate recesses p, the spring elements assisting in absorbing recoil shocks. If the elements are disposed near the middle of the plunger instead of at the rear end, they may slide in lengthened annular grooves or recesses in the casing, or the elements may be seated in the casing and the plunger be grooved. One or more buffing springs, or an arrangement of springs, Fig. 5, as described in Specification 352,694 may be employed, while the elements d and grooves may be given any suitable shape. Specification 297,180, [Class 103 (v), Railway &c. vehicles, Draught &c. appliances for], also is referred to
